在几次成功的 Selenium Geckodriver 任务 (Python) 之后，连接被拒绝（os 错误 111）

Question

OS: Ubuntu 20.04 无 GUI。

我正在无头模式下做一个非常简单的任务：

正在安装和启用 firefox 插件。
导航至 about:debugging#/runtime/this-firefox 并获取插件的 uuid。

问题是，在一些成功的 .py 脚本完成后，下一个就会挂起并且 return 连接被拒绝（os 错误 111）错误。之后我必须重新启动服务器，这只修复了几个 .py 脚本启动的问题。

我的代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium.webdriver import FirefoxProfile
import time

ff_options = FirefoxOptions()

user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) ff/85.0.4183.83 Safari/537.36"

ff_options.add_argument('-headless')
ff_options.add_argument(f'user-agent={user_agent}')
ff_options.add_argument('--disable-dev-shm-usage')
ff_options.add_argument('--no-sandbox')
ff_options.add_argument("--window-size=1920,1080")
ff_options.add_argument('--ignore-certificate-errors')
ff_options.add_argument('--allow-running-insecure-content')
ff_options.add_argument("--proxy-server='direct://'")
ff_options.add_argument("--proxy-bypass-list=*")
ff_options.add_argument("--start-maximized")
ff_options.add_argument('--disable-gpu')
ff_options.add_argument('--disable-setuid-sandbox')

buster = "/root/my_simple_extension.xpi"

driver = webdriver.Firefox(executable_path='/usr/local/share/geckodriver', options=ff_options)
driver.install_addon(buster, temporary=True)
driver.profile = webdriver.FirefoxProfile()
driver.profile.add_extension(buster)
driver.profile.set_preference("security.fileuri.strict_origin_policy", False)
driver.profile.update_preferences()

driver.get("about:debugging#/runtime/this-firefox")

time.sleep(1)

parent1 = driver.find_element_by_xpath('(//div[@class="fieldpair"])[position()=3]')
uuid = parent1.text.splitlines()[1]

driver.get('moz-extension://{}/home.html'.format(uuid))
time.sleep(1)
print(driver.page_source)
driver.quit()

Answer 1

只有测试的源代码并不能真正帮助为您的问题提供合格的答案。因此，请 create trace logs 在测试运行时与我们分享。记录到文件中的附加信息（在您的情况下应该是 geckodriver.log）可以帮助了解情况，并最终提出解决方案。谢谢

Answer 2

谢谢 furas 让我走上正轨。似乎在一些 python 代码错误之后， driver.quit() 没有被执行，这导致多个 firefox 进程挂起。使用 sudo pkill -9 firefox 退出它们解决了这个问题。
